Portulaca grandiflora is commonly known as Moss Rose. It has a great display of color for such a little ground cover plant! Moss Rose is a rewarding annual that is easy to grow and maintain. It makes a great edging plant for the front of a sunny border or grow it in containers and baskets. This mixed variety produces 1 inch, rose-like red, yellow and orange blooms that continue all summer long. The blooms open during the day and close at night and on cloudy days. Grow in full sun and in well-drained soil. Moss Rose can withstand heat and drought, but they perform best with an occasional deep watering. Trimming the plants during the summer will tidy their appearance and encourage blooming into fall.
